Add new [W13] logo design to Warehouse13

- Replace ◆ symbol with styled [W13] logo
- Logo uses monospace font with blue border and background
- Implemented in both Angular frontend and static HTML
- Added .logo CSS class with custom styling:
  - Courier New monospace font
  - Blue (#60a5fa) color and border
  - Semi-transparent background
  - Compact bracket style representing warehouse/storage containers

The logo maintains the warehouse/storage theme while being more distinctive and modern.
